00016 6/14/2016 - Everything is working!  115200 baud with array sizes of 32 bytes seems to be
00017             what is working reliably.
00018           - Keeping array sizes at 32 seems easy to send and receive over serial.  Trying
00019             to figure out why serial receive hangs with more than 32 bytes of data
00020             
00021 
00022 6/1/2016 - test to see if the recieve interrupt is handling the serial transfer and the
00023            read_line() does not need to be called
00024          - set up receive buffer to be stored into an array
00025            ... this will depend on where serial data is being received
